After a stop over in Wroclaw at a friend's I was stuck with the question, what to visit on my trip towards Cracow. Seeing Tarnowskie was on the way and scheduled for the WHC 2017 I figured, I may as well go and see it.
Frankly, what I got to see didn't really impress me at the time. I didn't even bother to write up a review, feeling this would be in vain. Yeah, yet another mine! The only unique feature I found was the boat ride they have on a canal deep in the mine which makes for a pleasant excursion. The picture is rather dark, but that's what it looks like. Still, pleasant does not indicate OUV.
Getting There
Tarnowskie can be reached by train from Wroclaw and Krakow. It is also connected via bus to Katowice. Bear in mind, though, that the mining museum is still quite a long walk away from the town center and train station. On the other hand, the town center has some historic buildings worthwhile visiting, emphasis being on some. Best transport information (as for all of Poland) are found at e-podroznik.pl.
At the museum there are regular tours that you can join, mostly in Polish, though. Check the schedule on their website.
While You Are There
You are in the Silesia and Cracow hotspots. For nearby Katowice two prospective sites are mentioned in our forum: the Cathedral of Christ the King and Nikiszowiec, a coal miner city. Katowice itself isn't all that nice.
